BURNER FOR ARGAND LAMPS.

Specification of Letters Patent No. 8,805, dated March 16, 1852.

To all whom it may concern:

Be it known that I, AUSTIN OLoor'r, of Rochester, in the county of Monroe and State of New York, have made certain new and useful Improvements in Lamps; and I do hereby declare that the same is described and represented in the following specification and accompanying drawings.

The nature of my invention consists in making the screw for traversing the wick of the lamp upon the outside of the interior tube of the lamp and making a thin tube with one or more grooves in it so as to just turn freely upon the outside of the screw; and making a wick holder to traverse outside of this tube with a pin or pins projecting from it on the inside through the groove in the tube into the score between the threads of the screw; and connecting this grooved tube at the top with a tube that passes down upon the inside of the tube which has the screw upon it and applying a fixture to this inside tube at the bottom to turn it and the grooved tube fastened to, so as to move the pin which projects from the wick holder into the score of the screw and traverse the wick holder with the wick upon the grooved tube as it may be required. and allow the material in the lamp which is to be burned to stand and flow freely around the wick without being obstructed by a perforated tube upon the outside of the wick. Also in adjusting the bottom of the chimney so far above the chimney holder or top of the lamp in proportion to its size so as to allow the air that passes in through this open space to contract the flame of the lamp andcarry. it up the chimney and at the same time allow a free emission and radiation of light from the flame thus saving the necessity of the conical cap or case heretofore used to contract the flame which greatly obstructed the free emission and radiation of light and consequently required a large consumption of the material burned in proportion to the amount of available light generated.

i To enable others skilled in the art to make and use my invention I will proceed to describe its construction and the mode of using it referring to the accompanying drawings, in which the same letters indicate like parts in all the figures.

Figure 1 is a view of the lamp with the chimney. Fig. 2 is a view with a portion of the several parts broken off soas to show its construction. Fig. 3 is a view of the lamp divided in the center. Fig. 4 is a view of the top of the lamp without the chimney holder; and Fig. 5 of the top of the wick holder.

A A outside tube of the lamp; B B inside tube with the screw upon it connected to the outside tube at the bottom by the flange b 6. These tubes are set a proper distance apart so as to leave the space G G between them for the oil, etc.

C C is a tube extending from the top to the bottom just large enough to turn freely upon the outside of the screw B B and is connected at the top by the rim E E to the inside tube D D, which extends down through the tube B B and has the rim H H fastened to it at the bottom by the rivets a a. The tube C C has two narrow openings one upon each side extending from the top nearly to the bottom in which the pins K K of the wick holder F F traverse, which pins are fastened into the wick holder and extend through the opening in the tube G into the score between the threads of the screw; so that as the tube G is turned the pins K K pass or are carried around in the score of the screw B and raise or lower the wick holder and wick. The wick holder is made in the form represented in the drawing and just large enough to traverse freely upon the tube C. The chimney holder is made in the form represented J J so as to fit the top of the tube A and has the supports L L L fastened to it, which hold the glass chimney I I a proper distance above thetop of the lamp so as to allow the air to draw in and supply the flame and pass up the chimney.

The lamp having been constructed as above described I fill the space G G nearly full of oil or the material to be burned and put a wick upon the wick holder and put it in and turn the tubes C and D by the flange H until the top of the wick is drawn down to within one eighth of an inch of the top of the lamp when it may be lighted and the chimney holder put on and the chimney set in its place.

I contemplate that the oil or material to be burned may be conducted from a cistern or vessel into the lamp by a tube in the usual manner.

lVhat I claim as my invention in the within described lamp, is

Arranging the grooved tube for adjusting ,on the outside, so that the material to be burned may have free and unobstructed ac- 10 cess around the wick.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.
